Factors Affecting the Application of Prefabrication in Construction Projects: A Sustainability Approach in Iran. دانشگاه علم و صنعت ایران. 1405; 36 (2)
چکیده:
Prefabrication, as an off-site construction approach, relocates key production processes from construction sites to controlled factory environments, offering significant advantages in efficiency, quality, and sustainability. Despite its growing global adoption, the criteria and prerequisites for its effective implementation remain insufficiently explored within the context of Iran. This study aims to identify and evaluate the critical factors influencing the application of prefabrication in Iran’s construction industry, with particular emphasis on sustainability considerations. A total of 26 criteria were identified through a comprehensive literature review and expert input. Data were collected via a structured survey administered to construction industry experts in Tehran. Exploratory factor analysis (EFA) was employed to determine the underlying factor structure, followed by confirmatory factor analysis (CFA) to validate the relationships between the identified factors and their influence on prefabrication adoption. The results indicate that five principal factors—construction and operational costs, constructability, external context, societal aspects, and environmental considerations—significantly influence the adoption of prefabrication. The first-order model demonstrates strong intercorrelations among these factors, highlighting their collective importance for stakeholders. Furthermore, the second-order model confirms that prefabrication adoption is closely associated with broader dimensions of Iran’s economy, society, environment, and construction culture. The findings contribute to the existing body of knowledge by contextualizing prefabrication adoption within a developing construction market and provide a structured framework to guide decision-making toward more sustainable construction practices in Iran.
